I would say only extremes will alter the top end of the draft, otherwise it shouldn't really change the order as it stands. I think some of the lower ranked players make bigger moves from the WJC than already top-ranked players.

Couturier dropped (in my opinion) because he had mono, and it affected him throughout the season I think. He was expected to take a bigger step in his draft year, but that kept him down a bit. I don't think he fell to 8th because of the WJC at all.
